The G20, or the Group of Twenty, is an international forum consisting of 19 countries and the European Union,

representing around 80% of the world's economic output, 75% of global trade, and two-thirds of the world's population. The G20 was established in 1999 to bring together major advanced and emerging economies to discuss and coordinate on global economic issues.

The G20 members are Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the United Kingdom, the United States, and the European Union.

India has been a member of the G20 since its inception in 1999. Being a part of the G20 provides India with several benefits, including:

Economic cooperation: As a member of the G20, India has a seat at the table where global economic policies and cooperation are discussed. This allows India to have a greater say in the global economic agenda and provides opportunities for collaboration with other G20 members.

Trade opportunities: The G20 countries account for a large share of global trade, and being a member provides India with opportunities to engage with other countries on trade and investment issues.

Access to resources: The G20 provides a platform for India to engage with other countries on issues related to energy, food security, and other natural resources.

Increased global visibility: Being a member of the G20 provides India with increased visibility on the global stage, which can help to attract foreign investment and boost the country's profile.

Policy coordination: The G20 provides a forum for India to coordinate policies with other major economies on issues such as climate change, terrorism, and global health. This can help to ensure that policies are consistent and coordinated across different countries.

Overall, being a member of the G20 provides India with a platform to engage with other major economies on global economic issues, which can help to promote economic growth and development in the country.
